1968 Montesa 250 Scorpion Motorcycle - Frames!

The new 250 Scorpion has a backbone to match the muscle of its engine. It is not a revise of the fast Montesa street machine, but it is a civilized version of the proved La Cross Scrambler. The Montesa engineers have taken advantage of both road racing and moto-cross experience to bring you the finest and fastest "on and off the road" motorcycle.

The frame is a rolled steel tube forming a full single loop. The Scorpion has in-built protection against rock damage to the engine, with smaller diameter tubes which run from the downtube to the top rear suspension mounts. This means that three tubes run underneath the engine. The tubes are linked by two steel plates - one on either side of the main tube - extensively drilled fro lightness. With all that surrounding armor, it is very unlikely that the Scorpion's sting could be blunted by even the largest of rocks.
